Hi Sean,

The absolute easiest way to go about a slow-moving motor would be to get one with a gearbox attached. The closest speed I could find to your target in our store is 6RPM, but you could likely get away with one with less reduction (more speed) and drive it with a PWM signal or lower voltage in order to slow it down.

> These standard gearmotors are incredibly tough and feature full metal gears to help you drive wheels, gears, or almost anything else that needs to turn. They have a gear ratio of 500:1 and operate up to 12 volts and deliver a stall torque of 613...

Using encoders and brushless motors will provide a truly silent experience, with excellent speed control, but such solutions are niche, and a little overpowered for what you’re looking to do I imagine:

Another option to consider would be stepper drivers with silent motor boards like the TMC2209, check out Geoff’s thread on his crane for his migration to silent step sticks:

> Thank you, I intend to pursue both of those suggestions. Nothing to lose as it functions at an acceptable level now. As always thanks for your contributions.

I wrote half of this post a while ago, and only just came back to it, so there is likely more I wanted to recommend, but have a look at what I’ve recommended so far and get back with your thoughts 🙂
